Question:

If a truck and a motorcycle get into a collision, how does the force from the motorcycle on the truck compare to the force from the truck on the motorcycle?

Brittany D.

Answer:

From Newton's Third Law, we know that each force results in an equal and opposite reaction. Thus, the two forces are equal in magnitude and opposite in direction.

Question:

How do you compute an indeterminate limit?

Brittany D.

Answer:
